Ukraine's air defences risk running out of missiles and ammunition within weeks, an apparent leak of Pentagon documents dating from February suggests, as US defence officials raced to trace how the files became public.

One of the documents, dated 23 February and marked Secret", outlines in detail how Ukraine's Soviet-era S-300 air defence systems would be depleted by 2 May at the current usage rate. It is unclear if the usage rate has since changed.
